Notice of the 44th "Latest Construction Method and Technology Training Seminar"

I would like to report on a new initiative that utilizes the cutting function of steel obstacles.

Yasuda Engineering Co., Ltd. will conduct a seminar at the 44th "Latest Construction Technology Seminar on Advanced Propulsion Methods" held in Tokyo and Osaka. We will report on our new initiatives utilizing the steel obstacle cutting function of the milling mole method. This seminar is accredited as a "Continuing Professional Development (CPD) Program" by the Japan Society of Civil Engineers. (CPD credits: 6.5) We sincerely look forward to your attendance. [Overview] ■ Seminar Time: 14:55 - 15:50 ■ Seminar Content: Challenging New Areas with the Milling Mole Method - New Initiatives Utilizing the Steel Obstacle Cutting Function - *For application details, please refer to [Details on How to Apply for Participation Here]. *For more information, please refer to the PDF document or feel free to contact us.

It is possible to directly reach the existing shield through the application of metal cutting technology! We are currently presenting examples of construction where direct cutting was performed on existing shields.

The "Milling Mole Method" is equipped with a specialized bit designed for cutting through obstacles using a tunneling machine. It allows the cutter of the tunneling machine to make ultra-low-speed contact with obstacles through a special telescopic pipe, enabling cutting through the rotation of the cutter. This operates on the same principle as lathe machining. A significant feature of this construction using the "Milling Mole Method" is that it achieved direct cutting of steel segments without performing mirror cutting. Since improvements to the protective measures of the existing shield section could not be made from the surface, a boring machine was mounted, allowing for injection from within the tunneling machine (using a dual-pipe strainer method with multiple phases). Additionally, a formwork for cutting connection was installed inside the existing shield, and fluidized treatment soil was placed, allowing for direct cutting at ultra-low speeds and safely avoiding the risks of water inflow and subsidence accidents that occur during mirror cutting. Previously, mirror cutting was performed from within the shield, raising concerns from customers about the risks to the surrounding environment due to groundwater inflow and ground collapse associated with that construction. We proposed direct cutting of the existing shield, and after executing the construction, we successfully reached the target without affecting water inflow or the surrounding environment, resulting in great satisfaction from the client! 《You can download the construction case from the PDF below!》

Introducing a case study of shield arrival construction using the milling mall method!

The "Milling Mole Method," equipped with four special functions: exploration, improvement, cutting, and guidance, is a ground obstacle response type mud-based thrusting method. It consists of three devices: a tunneling machine, a special telescopic pipe, and a special injection pipe, allowing for the precise cutting and removal of underground obstacles. In the construction of the inflow pipe sewer system for the second Nakagawa Chubu rainwater adjustment pond, the Milling Mole Method was used to carry out the shield arrival work. Milling cutting length: The assembly precision of the steel formwork at the arrival section inside the existing shield, L=1.520m from the outer circumference of the existing shield, was excellent, and there were no leaks of groundwater or muddy water during the placement of fluidized treated soil or during the shield cutting with the tunneling machine, allowing for safe cutting. 【Construction Example】 ■Location: Nagoya City, Aichi Prefecture ■Client: Nagoya City Waterworks Bureau ■Contractor: Asanuma Corporation ■Nominal Diameter: φ2200mm ■Thrusting Length: 101.520m ■Underground Obstacles: Direct access to the existing shield Inner diameter of the existing shield φ3750mm *For more details, please refer to the PDF document or feel free to contact us.

There are many programs available for management training, leadership training, and so on. This indicates that the needs of various companies are diverse, and the forms of solutions also differ. Our company regularly holds experiential seminars aimed at those responsible for or researching leadership training within each company, allowing them to experience the essence of management games. Please consider this as a solution for organizational challenges. The benefits of the experiential seminar are as follows: • You can experience the intrinsic value of management games. • You will understand the core of experiential training that cannot be conveyed through catalogs, brochures, or websites alone. • You can envision which programs should be applied to which job levels. • You can imagine the degree of growth of your employees after participating in the training. *This is aimed at those responsible for corporate education and training. Individuals seeking learning for personal purposes should participate in public seminars. [Request when applying] Please specify "via the Ipros site" when asked how you learned about our company.

Finally, the practical use of generative AI in the construction industry has been advancing. By utilizing generative AI, the operations in the construction industry have significantly improved, and many case studies have emerged. On the other hand, it is challenging to experiment with various tools, and there are not many courses specifically tailored for the construction industry. In this training, over two days, you will intensively learn generative AI practical skills specialized for construction, which you can immediately apply on-site starting the next day. This "super practical program" will allow you to quickly acquire skills to automate and streamline the creation of construction plans and presentation materials by utilizing the latest generative AI tools available for free, from the basic mechanisms of AI. It goes beyond mere technical introduction, enabling you to gain know-how that can be immediately used on-site through practical exercises directly related to your own work.

The Hokkaido Chamber of Commerce and Industry will hold an "Employee Skill Improvement Seminar" aimed at enhancing the skills of employees engaged in the construction industry and contributing to the stability of management. This seminar is recognized as a CPDS accredited training by the National Association of Civil Engineering Construction Management Engineers, and participants can earn 10 units by attending all lectures over the two days. Since this seminar is eligible for our subsidies, we encourage you to consider active participation.
